/* The live gate (/gate/, "Where it sits"). Example actions flow from your machine to your systems; each one is
   decided at the porcelain gate by the page's own classifier (pages/gate.js). The arch is drawn in an oblique view
   (tools: _work/innovate/shots/gate/arch.mjs), so a tile on the lane really passes through it: the back layer sits
   under the tiles, the near pillar (.lg-front) over them. Geometry in the arch's viewBox: hold line at x 56, floor at
   y 300, box 216 x 344; --s is pixels per unit. Colour keeps its meaning: green runs, vermilion only while held,
   ink blocked. Without JavaScript, and under reduced motion, three static tiles show one of each. */
